Question

There is some debate on influence of Jane Austen on Charlotte Bronte work as a writer (and in general on all three Bronte sisters'). If you are interested in finding more, feel free to google for their works and the debate. For this exercise, using the publicly available books on Project Gutenberg (http://www.eutenberg.org). you are asked to find the top 10 words and number of times they occur in books by Charlotte Bronte but not used by Jane Austen. To simply this exercise, we will only use the following books: HashMap (or HashTree) Java Collection will come handy for finding and keeping the count of words. You are only allowed to use Java Collections as described in Chapter 11 of our class textbook.
